  5. Mobile-First: Priority on small-screen experiences

Let’s implement these professional features!

Part 1: Understanding Header Layout Variations

Before diving into WordPress header customization code, let’s understand the three layouts we’ll build.

Layout Option 1: Default (Logo Left, Menu Right)

Use Cases:

  • Traditional business websites
  • E-commerce stores
  • Corporate sites
  • Portfolio websites

Characteristics:

  • Logo/branding on left
  • Navigation menu on right
  • Horizontal space optimization
  • Industry standard layout

Layout Option 2: Centered (Stacked Layout)

Use Cases:

  • Creative agencies
  • Photography portfolios
  • Fashion blogs
  • Restaurants/hospitality

Characteristics:

  • Logo centered at top
  • Menu centered below logo
  • Elegant, balanced appearance
  • Fashion/luxury brand aesthetic

Layout Option 3: Minimal (Compact with Hamburger)

Use Cases:

  • Minimalist blogs
  • Single-page websites
  • Mobile-first applications
  • Content-focused sites

Characteristics:

  • Ultra-compact header
  • Always uses hamburger menu
  • Maximum content space
  • Modern, clean appearance

Part 2: Implementing Header Layout Variations

Let’s start with the CSS for our WordPress header customization system.

Step 1: Update Header CSS File

Open assets/css/header.css and add these layout styles:

/**
 * Header Layout Variations
 * Core styles for WordPress header customization
 */

/* ==========================================================================
   Default Layout - Logo Left, Menu Right
   ========================================================================== */

.header-layout-default .site-header {
    /* Base WordPress FSE styles apply */
}

.header-layout-default .site-header .wp-block-group__inner-container {
    display: flex;
    align-items: center;
    justify-content: space-between;
    flex-wrap: wrap;
    gap: var(--wp--preset--spacing--30, 1rem);
}

/* Ensure logo and menu are properly aligned */
.header-layout-default .wp-block-site-logo,
.header-layout-default .wp-block-site-title {
    margin-right: auto;
}

.header-layout-default .wp-block-navigation {
    margin-left: auto;
}

CSS Explanation for Beginners:

  1. .header-layout-default – This class is added to the <body> tag when users select the default layout
  2. display: flex – Creates a flexible container for logo and menu
  3. justify-content: space-between – Pushes logo left, menu right
  4. flex-wrap: wrap – Allows wrapping on small screens
  5. gap – Adds spacing between items using WordPress spacing presets

Step 2: Centered Layout Styles

Add this for centered WordPress header customization:

/* ==========================================================================
   Centered Layout - Stacked Design
   ========================================================================== */

.header-layout-centered .site-header {
    text-align: center;
}

.header-layout-centered .site-header .wp-block-group__inner-container {
    display: flex;
    flex-direction: column;
    align-items: center;
    gap: var(--wp--preset--spacing--40, 1.5rem);
}

.header-layout-centered .wp-block-site-logo {
    margin-left: auto;
    margin-right: auto;
}

.header-layout-centered .wp-block-site-title {
    text-align: center;
}

.header-layout-centered .wp-block-navigation {
    justify-content: center;
}

.header-layout-centered .wp-block-navigation__container {
    justify-content: center;
}

/* Center navigation items */
.header-layout-centered .wp-block-navigation-item {
    margin: 0 var(--wp--preset--spacing--20, 0.5rem);
}

Key Techniques:

  • flex-direction: column – Stacks elements vertically
  • align-items: center – Centers everything horizontally
  • margin: auto – Traditional CSS centering for logo
  • justify-content: center – Centers navigation items

Step 3: Minimal Layout Styles

The compact header for maximum content space:

/* ==========================================================================
   Minimal Layout - Compact & Clean
   ========================================================================== */

.header-layout-minimal .site-header {
    padding-top: var(--wp--preset--spacing--30, 1rem);
    padding-bottom: var(--wp--preset--spacing--30, 1rem);
}

.header-layout-minimal .site-header .wp-block-group__inner-container {
    display: flex;
    align-items: center;
    justify-content: space-between;
}

/* Smaller logo for minimal design */
.header-layout-minimal .wp-block-site-logo img {
    max-height: 40px;
    width: auto;
}

.header-layout-minimal .wp-block-site-title {
    font-size: var(--wp--preset--font-size--medium, 1.25rem);
    line-height: 1.2;
}

/* Always show hamburger menu in minimal layout */
.header-layout-minimal .wp-block-navigation__responsive-container:not(.is-menu-open) {
    display: none;
}

.header-layout-minimal .wp-block-navigation__responsive-container-open {
    display: flex !important;
}

@media (min-width: 782px) {
    /* Show hamburger on desktop too */
    .header-layout-minimal .wp-block-navigation__responsive-container-open {
        display: flex;
    }
    
    .header-layout-minimal .wp-block-navigation__responsive-container.is-menu-open {
        display: flex;
    }
}

Design Decisions:

  • Reduced Padding: Creates compact appearance
  • Smaller Logo: 40px height vs. standard 60px
  • Always Hamburger: Even on desktop for consistent UX
  • Font Size Reduction: Matches compact aesthetic

Step 4: Adding Dynamic Body Classes

These layouts need corresponding body classes. Open inc/template-functions.php:

/**
 * Add header layout class to body
 *
 * Part of WordPress header customization system
 */
function versana_body_classes( $classes ) {
    
    // Get header layout from theme options
    $header_layout = versana_get_option( 'header_layout', 'default' );
    $classes[] = 'header-layout-' . sanitize_html_class( $header_layout );
    
    return $classes;
}
add_filter( 'body_class', 'versana_body_classes' );

How This Works:

  1. WordPress calls body_class() filter when rendering <body> tag
  2. We retrieve the user’s selected layout from theme options
  3. We sanitize the value for security
  4. We add class like header-layout-centered to body
  5. CSS targets this class to apply appropriate styles

Part 3: Mobile Menu Styles – Overlay vs. Drawer

Mobile navigation is critical for WordPress header customization. Let’s build two professional styles.

Understanding Mobile Menu Patterns

Full Screen Overlay:

  • Takes over entire screen
  • Centers content
  • Best for: content-focused sites, photography, fashion

Slide-in Drawer:

  • Slides in from right (or left)
  • Shows alongside content
  • Best for: e-commerce, dashboards, apps

Step 1: Create Mobile Menu CSS File

Create assets/css/mobile-menu.css:

/**
 * Mobile Menu Styles
 * Advanced WordPress header customization for mobile navigation
 *
 * @package Versana
 */

/* ==========================================================================
   Mobile Menu Foundation
   ========================================================================== */

/* Backdrop overlay for both menu styles */
.mobile-menu-overlay-backdrop {
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background: rgba(0, 0, 0, 0.5);
    z-index: 9998;
    opacity: 0;
    visibility: hidden;
    transition: opacity 0.3s ease, visibility 0.3s ease;
    backdrop-filter: blur(4px);
}

.mobile-menu-overlay-backdrop.is-visible {
    opacity: 1;
    visibility: visible;
}

CSS Properties Explained:

  • position: fixed – Stays in place during scroll
  • z-index: 9998 – Below menu (9999) but above content
  • backdrop-filter: blur(4px) – Modern glassmorphism effect
  • visibility: hidden – Removes from accessibility tree when closed

Step 2: Full Screen Overlay Menu

/* ==========================================================================
   Full Screen Overlay Menu
   ========================================================================== */

.mobile-menu-overlay .wp-block-navigation__responsive-container.is-menu-open {
    position: fixed;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
    background: var(--wp--preset--color--base, #ffffff);
    z-index: 99999;
    display: flex;
    align-items: center;
    justify-content: center;
    padding: 2rem;
    overflow-y: auto;
    animation: fadeIn 0.3s ease;
}

/* Content wrapper for menu items */
.mobile-menu-overlay .wp-block-navigation__responsive-container-content {
    width: 100%;
    max-width: 600px;
    padding: 2rem 0;
}

/* Vertical menu layout */
.mobile-menu-overlay .wp-block-navigation__container {
    display: flex;
    flex-direction: column;
    gap: var(--wp--preset--spacing--40, 1.5rem);
}

/* Large, centered menu items */
.mobile-menu-overlay .wp-block-navigation-item {
    text-align: center;
}

.mobile-menu-overlay .wp-block-navigation-item__content {
    font-size: var(--wp--preset--font-size--large, 1.5rem);
    font-weight: 600;
    padding: 0.75rem 1rem;
    display: block;
    transition: all 0.2s ease;
}

.mobile-menu-overlay .wp-block-navigation-item__content:hover {
    transform: scale(1.05);
    color: var(--wp--preset--color--primary, #000);
}

/* Close button styling */
.mobile-menu-overlay .wp-block-navigation__responsive-container-close {
    position: absolute;
    top: 2rem;
    right: 2rem;
    z-index: 100000;
    width: 44px;
    height: 44px;
    display: flex;
    align-items: center;
    justify-content: center;
}

/* Fade in animation */
@keyframes fadeIn {
    from {
        opacity: 0;
    }
    to {
        opacity: 1;
    }
}

Design Principles:

  • Large Touch Targets: 44px minimum for accessibility
  • Generous Spacing: Easy to tap without mistakes
  • Center Alignment: Draws focus to navigation
  • Smooth Animations: Professional feel

Step 3: Slide-in Drawer Menu

/* ==========================================================================
   Slide-in Drawer Menu
   ========================================================================== */

.mobile-menu-drawer .wp-block-navigation__responsive-container {
    position: fixed;
    top: 0;
    right: -100%;
    bottom: 0;
    width: 85%;
    max-width: 400px;
    background: var(--wp--preset--color--base, #ffffff);
    z-index: 99999;
    box-shadow: -2px 0 20px rgba(0, 0, 0, 0.15);
    transition: right 0.3s cubic-bezier(0.4, 0.0, 0.2, 1);
    overflow-y: auto;
}

.mobile-menu-drawer .wp-block-navigation__responsive-container.is-menu-open {
    right: 0;
}

/* Content padding */
.mobile-menu-drawer .wp-block-navigation__responsive-container-content {
    padding: 2rem;
    padding-top: 4rem;
}

/* Vertical stacked layout */
.mobile-menu-drawer .wp-block-navigation__container {
    display: flex;
    flex-direction: column;
    gap: var(--wp--preset--spacing--30, 1rem);
}

/* Menu item styling */
.mobile-menu-drawer .wp-block-navigation-item__content {
    padding: 0.75rem 1rem;
    display: block;
    border-radius: var(--wp--preset--spacing--20, 0.375rem);
    transition: background-color 0.2s ease;
}

.mobile-menu-drawer .wp-block-navigation-item__content:hover {
    background-color: var(--wp--preset--color--contrast, rgba(0, 0, 0, 0.05));
}

/* Active/current menu item */
.mobile-menu-drawer .current-menu-item .wp-block-navigation-item__content {
    background-color: var(--wp--preset--color--primary, #000);
    color: var(--wp--preset--color--base, #fff);
}

/* Close button for drawer */
.mobile-menu-drawer .wp-block-navigation__responsive-container-close {
    position: absolute;
    top: 1rem;
    right: 1rem;
    z-index: 100000;
}

/* Smooth cubic-bezier for natural motion */
@keyframes slideInFromRight {
    from {
        transform: translateX(100%);
    }
    to {
        transform: translateX(0);
    }
}

Advanced CSS Techniques:

  • cubic-bezier(0.4, 0.0, 0.2, 1) – Material Design easing curve
  • Negative Position: -100% hides drawer off-screen
  • Transform vs Position: We use position for drawer, transform for other animations
  • Box Shadow: Creates depth perception

Step 4: Responsive Breakpoints

Add desktop resets:

/* ==========================================================================
   Desktop Reset - Important!
   ========================================================================== */

@media (min-width: 782px) {
    /* Reset mobile menu styles on desktop */
    .mobile-menu-overlay .wp-block-navigation__responsive-container,
    .mobile-menu-drawer .wp-block-navigation__responsive-container {
        position: static;
        transform: none;
        width: auto;
        max-width: none;
        background: transparent;
        box-shadow: none;
        padding: 0;
        overflow: visible;
    }
    
    /* Horizontal menu on desktop */
    .mobile-menu-overlay .wp-block-navigation__container,
    .mobile-menu-drawer .wp-block-navigation__container {
        flex-direction: row;
        gap: var(--wp--preset--spacing--30, 1rem);
    }
    
    /* Reset font sizes */
    .mobile-menu-overlay .wp-block-navigation-item__content,
    .mobile-menu-drawer .wp-block-navigation-item__content {
        font-size: inherit;
        font-weight: inherit;
        padding: 0.5rem 1rem;
    }
    
    /* Hide backdrop on desktop */
    .mobile-menu-overlay-backdrop {
        display: none;
    }
}

Why This Matters:

Mobile-first CSS can conflict with desktop layouts. These resets ensure:

  • Desktop navigation displays normally
  • No unwanted animations or transitions
  • Proper horizontal layout
  • Standard menu styling

Step 5: Mobile Menu JavaScript

Update assets/js/header.js to handle mobile menus:

/**
 * Initialize mobile menu enhancements
 * Part of WordPress header customization system
 */
function initMobileMenu() {
    const menuToggle = document.querySelector('.wp-block-navigation__responsive-container-open');
    const menuClose = document.querySelector('.wp-block-navigation__responsive-container-close');
    const menuContainer = document.querySelector('.wp-block-navigation__responsive-container');
    
    if (!menuToggle || !menuContainer) {
        return;
    }
    
    // Check if overlay or drawer style is active
    const isOverlay = document.body.classList.contains('mobile-menu-overlay');
    const isDrawer = document.body.classList.contains('mobile-menu-drawer');
    
    if (!isOverlay && !isDrawer) {
        return; // Default WordPress menu behavior
    }
    
    // Create backdrop element
    const backdrop = document.createElement('div');
    backdrop.className = 'mobile-menu-overlay-backdrop';
    backdrop.setAttribute('aria-hidden', 'true');
    
    // Show backdrop when menu opens
    menuToggle.addEventListener('click', function() {
        // Small delay to ensure menu has 'is-menu-open' class
        setTimeout(function() {
            if (menuContainer.classList.contains('is-menu-open')) {
                document.body.appendChild(backdrop);
                
                // Trigger animation
                requestAnimationFrame(function() {
                    backdrop.classList.add('is-visible');
                });
                
                // Prevent body scroll
                document.body.style.overflow = 'hidden';
                
                // Update ARIA
                menuToggle.setAttribute('aria-expanded', 'true');
            }
        }, 50);
    });
    
    // Close menu function
    function closeMenu() {
        backdrop.classList.remove('is-visible');
        
        // Wait for animation then remove backdrop
        setTimeout(function() {
            if (backdrop.parentNode) {
                backdrop.parentNode.removeChild(backdrop);
            }
        }, 300);
        
        // Restore body scroll
        document.body.style.overflow = '';
        
        // Update ARIA
        menuToggle.setAttribute('aria-expanded', 'false');
    }
    
    // Close when clicking backdrop
    backdrop.addEventListener('click', function() {
        if (menuClose) {
            menuClose.click();
        }
        closeMenu();
    });
    
    // Close when clicking close button
    if (menuClose) {
        menuClose.addEventListener('click', closeMenu);
    }
    
    // Close on escape key
    document.addEventListener('keydown', function(e) {
        if (e.key === 'Escape' && menuContainer.classList.contains('is-menu-open')) {
            if (menuClose) {
                menuClose.click();
            }
            closeMenu();
            menuToggle.focus(); // Return focus to toggle
        }
    });
    
    // Close menu when clicking a link (improves UX)
    const menuLinks = menuContainer.querySelectorAll('a');
    menuLinks.forEach(function(link) {
        link.addEventListener('click', function() {
            // Only close if it's a regular link (not submenu toggle)
            if (!link.classList.contains('wp-block-navigation-item__content--has-submenu')) {
                setTimeout(closeMenu, 100);
            }
        });
    });
}

JavaScript Features Explained:

  1. Backdrop Creation: Dynamic element added when menu opens
  2. Body Scroll Lock: Prevents scrolling when menu is open
  3. ARIA Updates: Proper aria-expanded attributes for accessibility
  4. Escape Key: Keyboard accessibility
  5. Link Click Close: Automatically closes menu after navigation
  6. Focus Management: Returns focus to toggle button on close

Part 4: Header Search Functionality

Integrated search is essential for modern WordPress header customization.

Step 1: Header Search CSS

Add to assets/css/header.css:

/* ==========================================================================
   Header Search - WordPress Header Customization
   ========================================================================== */

.header-search-wrapper {
    position: relative;
    display: none;
}

/* Show when enabled in theme options */
body.has-header-search .header-search-wrapper {
    display: block;
}

/* Search toggle button */
.header-search-toggle {
    background: transparent;
    border: none;
    padding: 0.5rem;
    cursor: pointer;
    display: flex;
    align-items: center;
    justify-content: center;
    color: var(--wp--preset--color--contrast, #000);
    transition: opacity 0.2s ease, transform 0.2s ease;
    border-radius: 50%;
    width: 44px;
    height: 44px;
}

.header-search-toggle:hover {
    opacity: 0.7;
    transform: scale(1.1);
}

.header-search-toggle:focus {
    outline: 2px solid var(--wp--preset--color--primary, #000);
    outline-offset: 2px;
}

.header-search-toggle svg {
    width: 20px;
    height: 20px;
}

/* Search form dropdown */
.header-search-form {
    position: absolute;
    top: calc(100% + 1rem);
    right: 0;
    background: var(--wp--preset--color--base, #ffffff);
    padding: 1.5rem;
    border-radius: var(--wp--preset--spacing--30, 0.5rem);
    box-shadow: 0 4px 20px rgba(0, 0, 0, 0.15);
    min-width: 320px;
    opacity: 0;
    visibility: hidden;
    transform: translateY(-10px);
    transition: opacity 0.3s ease, visibility 0.3s ease, transform 0.3s ease;
    z-index: 1000;
}

.header-search-form.is-active {
    opacity: 1;
    visibility: visible;
    transform: translateY(0);
}

/* Search input */
.header-search-form input[type="search"] {
    width: 100%;
    padding: 0.75rem 3rem 0.75rem 1rem;
    border: 2px solid var(--wp--preset--color--contrast, rgba(0, 0, 0, 0.2));
    border-radius: var(--wp--preset--spacing--20, 0.375rem);
    font-size: 1rem;
    background: var(--wp--preset--color--base, #ffffff);
    transition: border-color 0.2s ease, box-shadow 0.2s ease;
}

.header-search-form input[type="search"]:focus {
    outline: none;
    border-color: var(--wp--preset--color--primary, #000);
    box-shadow: 0 0 0 3px rgba(0, 0, 0, 0.1);
}

/* Search submit button */
.header-search-form button[type="submit"] {
    position: absolute;
    right: 2rem;
    top: 50%;
    transform: translateY(-50%);
    background: transparent;
    border: none;
    padding: 0.5rem;
    cursor: pointer;
    color: var(--wp--preset--color--contrast, #000);
    transition: opacity 0.2s ease;
    display: flex;
    align-items: center;
    justify-content: center;
}

.header-search-form button[type="submit"]:hover {
    opacity: 0.7;
}

.header-search-form button[type="submit"] svg {
    width: 20px;
    height: 20px;
}

Step 2: Mobile Search Styles

/* ==========================================================================
   Mobile Header Search
   ========================================================================== */

@media (max-width: 781px) {
    /* Full screen search on mobile */
    .header-search-form {
        position: fixed;
        top: 0;
        left: 0;
        right: 0;
        bottom: auto;
        margin: 0;
        border-radius: 0;
        min-width: auto;
        padding: 1rem;
        box-shadow: 0 2px 10px rgba(0, 0, 0, 0.1);
        min-height: 80px;
        display: flex;
        align-items: center;
    }
    
    .header-search-form.is-active {
        transform: translateY(0);
    }
    
    /* Prevent iOS zoom */
    .header-search-form input[type="search"] {
        font-size: 16px;
    }
    
    /* Mobile close button */
    .header-search-form::before {
        content: "×";
        position: absolute;
        top: 1rem;
        right: 1rem;
        font-size: 2rem;
        line-height: 1;
        cursor: pointer;
        width: 44px;
        height: 44px;
        display: flex;
        align-items: center;
        justify-content: center;
        color: var(--wp--preset--color--contrast, #000);
        background: transparent;
        border-radius: 50%;
        transition: background-color 0.2s ease;
    }
    
    .header-search-form::before:hover {
        background-color: rgba(0, 0, 0, 0.05);
    }
}

Mobile Optimization Notes:

  • font-size: 16px – Prevents iOS from zooming on input focus
  • Fixed positioning – Takes over top of screen
  • Close button – Created with CSS pseudo-element
  • Touch-friendly – 44px minimum tap targets

Step 3: Search JavaScript Enhancement

Add to assets/js/header.js:

/**
 * Initialize header search functionality
 * Enhanced for WordPress header customization
 */
function initHeaderSearch() {
    const searchToggle = document.querySelector('.header-search-toggle');
    const searchForm = document.querySelector('.header-search-form');
    
    if (!searchToggle || !searchForm) {
        return;
    }
    
    // Open search
    function openSearch() {
        searchForm.classList.add('is-active');
        searchToggle.setAttribute('aria-expanded', 'true');
        
        // Focus input after animation
        setTimeout(function() {
            const searchInput = searchForm.querySelector('input[type="search"]');
            if (searchInput) {
                searchInput.focus();
            }
        }, 100);
        
        // Prevent body scroll on mobile
        if (window.innerWidth <= 781) {
            document.body.style.overflow = 'hidden';
        }
    }
    
    // Close search
    function closeSearch() {
        searchForm.classList.remove('is-active');
        searchToggle.setAttribute('aria-expanded', 'false');
        document.body.style.overflow = '';
    }
    
    // Toggle button click
    searchToggle.addEventListener('click', function(e) {
        e.preventDefault();
        e.stopPropagation();
        
        if (searchForm.classList.contains('is-active')) {
            closeSearch();
        } else {
            openSearch();
        }
    });
    
    // Close on outside click
    document.addEventListener('click', function(e) {
        if (!searchForm.contains(e.target) && 
            !searchToggle.contains(e.target) &&
            searchForm.classList.contains('is-active')) {
            closeSearch();
        }
    });
    
    // Close on escape key
    document.addEventListener('keydown', function(e) {
        if (e.key === 'Escape' && searchForm.classList.contains('is-active')) {
            closeSearch();
            searchToggle.focus();
        }
    });
    
    // Mobile close button
    if (window.innerWidth <= 781) {
        searchForm.addEventListener('click', function(e) {
            const rect = searchForm.getBoundingClientRect();
            const closeArea = {
                left: rect.right - 60,
                right: rect.right - 10,
                top: rect.top + 10,
                bottom: rect.top + 60
            };
            
            // Check if click is in close button area
            if (e.clientX >= closeArea.left && 
                e.clientX <= closeArea.right &&
                e.clientY >= closeArea.top && 
                e.clientY <= closeArea.bottom) {
                closeSearch();
            }
        });
    }
}

Step 4: Create Header Search Helper Function

Create inc/header-search.php:

<?php
/**
 * Header Search Functions
 * WordPress header customization helper functions
 *
 * @package Versana
 * @since 1.0.0
 */

if ( ! defined( 'ABSPATH' ) ) {
    exit;
}

/**
 * Render header search UI
 *
 * Outputs complete search toggle and form
 * Only displays if enabled in theme options
 */
function versana_render_header_search() {
    
    if ( ! versana_get_option( 'enable_header_search' ) ) {
        return;
    }
    
    ?>
    <div class="header-search-wrapper">
        
        <!-- Search Toggle Button -->
        <button class="header-search-toggle" 
                aria-label="<?php esc_attr_e( 'Toggle search', 'versana' ); ?>" 
                aria-expanded="false"
                aria-controls="header-search-form">
            <svg xmlns="http://www.w3.org/2000/svg"

                <path d="m21 21-4.35-4.35"></path>
            </svg>
            <span class="screen-reader-text">

        <!-- Search Form -->
        <div class="header-search-form" 
             id="header-search-form"
             role="search">
            <form method="get" 
                  action="<?php echo esc_url( home_url( '/' ) ); ?>">
                <label for="header-search-input" class="screen-reader-text">

                    placeholder="<?php esc_attr_e( 'Search...', 'versana' ); ?>" 
                    value="<?php echo esc_attr( get_search_query() ); ?>"
                    autocomplete="off"

                />
                <button type="submit" 
                        aria-label="<?php esc_attr_e( 'Submit search', 'versana' ); ?>">
                    <svg xmlns="http://www.w3.org/2000/svg" 
                         width="20" 
                         height="20" 
                         viewBox="0 0 24 24" 
                         fill="none" 
                         stroke="currentColor"

 */
function versana_header_search_shortcode() {
    ob_start();
    versana_render_header_search();
    return ob_get_clean();
}
add_shortcode( 'versana_header_search', 'versana_header_search_shortcode' );

Accessibility Features:

  • ARIA labels on all interactive elements
  • aria-expanded for toggle state
  • aria-controls links button to form
  • Screen reader text for icon buttons
  • Keyboard navigation with Escape key
  • Focus management after open/close

Part 5: Conditional Asset Loading

Performance-optimized WordPress header customization requires smart asset loading.

Update inc/enqueue.php

<?php
/**
 * Conditional asset enqueuing
 * Only load CSS/JS when features are enabled
 */
function versana_enqueue_dynamic_assets() {
    
    // Header CSS - Load if any header customization is active
    if ( versana_get_option( 'enable_sticky_header' ) || 
         versana_get_option( 'enable_header_search' ) ||
         versana_get_option( 'header_layout' ) !== 'default' ) {
        
        wp_enqueue_style(
            'versana-header',
            get_template_directory_uri() . '/assets/css/header.css',
            array(),
            VERSANA_VERSION
        );
    }
    
    // Mobile menu CSS - Only if custom style selected
    $mobile_menu_style = versana_get_option( 'mobile_menu_style', 'default' );
    if ( in_array( $mobile_menu_style, array( 'overlay', 'drawer' ) ) ) {
        wp_enqueue_style(
            'versana-mobile-menu',
            get_template_directory_uri() . '/assets/css/mobile-menu.css',
            array(),
            VERSANA_VERSION
        );
    }
    
    // Header JavaScript
    if ( versana_get_option( 'enable_sticky_header' ) || 
         versana_get_option( 'enable_header_search' ) ||
         in_array( $mobile_menu_style, array( 'overlay', 'drawer' ) ) ) {
        
        wp_enqueue_script(
            'versana-header',
            get_template_directory_uri() . '/assets/js/header.js',
            array(),
            VERSANA_VERSION,
            true
        );
    }
}
add_action( 'wp_enqueue_scripts', 'versana_enqueue_dynamic_assets' );

Advanced Customization Tips

Tip 1: Custom Animation Timing

:root {
    --header-transition-duration: 0.3s;
    --header-transition-easing: cubic-bezier(0.4, 0.0, 0.2, 1);
}

.header-search-form {
    transition: 
        opacity var(--header-transition-duration) var(--header-transition-easing),
        visibility var(--header-transition-duration) var(--header-transition-easing),
        transform var(--header-transition-duration) var(--header-transition-easing);
}

Tip 2: Mega Menu Support

.header-layout-default .wp-block-navigation__submenu-container {
    width: 100%;
    max-width: 1200px;
    left: 50%;
    transform: translateX(-50%);
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    gap: 2rem;
    padding: 2rem;
}

Tip 3: Sticky Search Bar

.header-layout-minimal.has-sticky-header .header-search-form {
    position: fixed;
    top: calc(var(--header-height) + 1rem);
    right: 1rem;
}

Tip 4: Search Autocomplete

// Add to header.js
function initSearchAutocomplete() {
    const searchInput = document.querySelector('#header-search-input');
    if (!searchInput) return;
    
    let timeout;
    searchInput.addEventListener('input', function(e) {
        clearTimeout(timeout);
        timeout = setTimeout(function() {
            fetchSearchSuggestions(e.target.value);
        }, 300);
    });
}

function fetchSearchSuggestions(query) {
    if (query.length < 3) return;
    
    fetch(`/wp-json/wp/v2/search?search=${query}&per_page=5`)
        .then(res => res.json())
        .then(results => displaySuggestions(results))
        .catch(err => console.error('Search error:', err));
}

Performance Optimization

Measuring Impact

Use Chrome DevTools Performance tab:

// Measure menu animation performance
performance.mark('menu-open-start');
// ... open menu code ...
performance.mark('menu-open-end');
performance.measure('Menu Open', 'menu-open-start', 'menu-open-end');

const menuOpenTime = performance.getEntriesByName('Menu Open')[0].duration;
console.log(`Menu opened in ${menuOpenTime}ms`);

Target Metrics:

  • Menu animation: < 300ms
  • Search toggle: < 100ms
  • Layout switch: Instant (0-frame)
  • Scroll performance: 60fps

Optimization Techniques

1. CSS Containment:

.site-header {
    contain: layout style paint;
}

2. Will-Change Hints:

.mobile-menu-drawer .wp-block-navigation__responsive-container {
    will-change: right;
}

3. Passive Event Listeners:

element.addEventListener('scroll', handler, { passive: true });

4. Debounce Expensive Operations:

function debounce(func, wait) {
    let timeout;
    return function executedFunction(...args) {
        const later = () => {
            clearTimeout(timeout);
            func(...args);
        };
        clearTimeout(timeout);
        timeout = setTimeout(later, wait);
    };
}

Troubleshooting Common Issues

Issue #1: Layout Not Changing

Symptoms:

  • Selected layout in admin
  • Saved successfully
  • No visual change on frontend

Solutions:

  1. Check body class: Inspect <body> tag for header-layout-{name}
  2. Clear all caches: Browser, WordPress, CDN
  3. Verify CSS is loading: Check Network tab
  4. Check theme options retrieval:
// Add to template
var_dump( versana_get_option( 'header_layout' ) );

Issue #2: Mobile Menu Not Sliding

Symptoms:

  • Menu appears instantly
  • No animation
  • Backdrop missing

Solutions:

  1. Verify JavaScript is loaded and executing
  2. Check console for errors
  3. Ensure body class is correct: mobile-menu-drawer or mobile-menu-overlay
  4. Test CSS transitions:
/* Add temporarily for debugging */
* {
    transition: all 0.3s ease !important;
}

Issue #3: Search Not Opening

Symptoms:

  • Click toggle button
  • Nothing happens
  • No console errors

Solutions:

  1. Verify has-header-search class on body
  2. Check JavaScript initialization:
// Add to header.js
console.log('Search initialized:', !!document.querySelector('.header-search-toggle'));
  1. Ensure CSS is loaded
  2. Check z-index stacking

Issue #4: Performance Issues

Symptoms:

  • Janky animations
  • Slow menu open
  • Laggy scroll

Solutions:

  1. Use Chrome Performance Profiler
  2. Check for:
    • Too many repaints
    • JavaScript blocking main thread
    • Large DOM size
    • Conflicting CSS animations
  3. Enable hardware acceleration:
.site-header {
    transform: translateZ(0);
    backface-visibility: hidden;
}

Accessibility Best Practices

WCAG 2.1 Compliance Checklist

  • [x] Keyboard Navigation: All interactive elements accessible via keyboard
  • [x] Focus Indicators: Clear visual focus on interactive elements
  • [x] ARIA Labels: Proper labeling for screen readers
  • [x] Color Contrast: Minimum 4.5:1 ratio for text
  • [x] Touch Targets: Minimum 44x44px for mobile
  • [x] Skip Links: Allow bypassing navigation
  • [x] No Timeouts: Menus don’t auto-close unexpectedly

Screen Reader Testing

Test with:

  • NVDA (Windows, Free)
  • JAWS (Windows, Commercial)
  • VoiceOver (Mac/iOS, Built-in)
  • TalkBack (Android, Built-in)

Expected Announcements:

  • “Search, button, collapsed” (toggle closed)
  • “Search, button, expanded” (toggle open)
  • “Search for: edit text” (input focused)
  • “Navigation, region” (main menu)

SEO Considerations

Structured Data for Header

function versana_add_header_schema() {
    if ( ! is_front_page() ) {
        return;
    }
    ?>
    <script type="application/ld+json">
    {
        "@context": "https://schema.org",
        "@type": "WPHeader",
        "headline": "<?php echo esc_js( get_bloginfo( 'name' ) ); ?>",
        "url": "<?php echo esc_url( home_url( '/' ) ); ?>",
        "potentialAction": {
            "@type": "SearchAction",
            "target": "<?php echo esc_url( home_url( '/?s={search_term_string}' ) ); ?>",
            "query-input": "required name=search_term_string"
        }
    }
    </script>
    <?php
}
add_action( 'wp_head', 'versana_add_header_schema' );

Navigation Best Practices
